Answer:
40 individuals
Explanation:
The homozygous recessive percentage is equal to q2.
Recessive genotype frequency, q 2 is 1/1000000 = 0.000001
therefore, q = 
= 
= 0.001 = allele "a" frequency
and p + q = 1, thus, p = 1 – q = 1 – 0.001 = 0.999
thus, the frequency of allele a = q = 0.001 and the frequency of allele A = p = 0.999
Carriers are heterozygous and are equal to 2pq.
So, 2pq = 2 x 0.999 x 0.001 x 20,000 = 39.96 (round of to 40)
Hence, 40 individuals will be expected to carry the recessive allele.
I think A is the youngest layer, because of the new sediments that fell upon the animal.
I would support the factory if I lived 50 miles away from the planned factory location. However, I would be worried if I only lived one mile away from the planned factory, because of possible health effects, bad smells, and a potential decrease in property values.
<h3>What is Air pollution ?</h3>
Factories contaminate the air by blowing chemical vapors and smoke out through vents and smokestacks, and by burning waste in open dumps or incinerators.
- Exhaust from generators, diesel trucks, and buses also fill the air with dangerous gases.
- The amount of toxic gases that factories release into the air increases health and environmental damages. In factories, toxic materials and gases, like carbon dioxide and methane, are burned and pumped out into the atmosphere.
